制备了一种新型的防热隔热一体化材料-碳-高硅氧纤维增强C-SiC复合材料,沿厚度方向从抗烧蚀层渐次过渡到隔热层,其组成依次是致密C/C-SiC,致密C/C,多孔C/C,通过界面处过渡到变密度多孔HSF/C.这种材料既具有抗烧蚀性能又具有隔热性能.C/C-SiC复合材料的烧蚀表面平滑,线烧蚀率只有0.028 mm/s.烧蚀性能的提高得益于SiC颗粒原位氧化生成SiO2黏附在碳材料表面,对氧气有一定的阻挡遮蔽作用.密度为0.80 g/cm3的HSF/C材料,热导率为0.59W/mK.在碳纤维与高硅氧织物的界面处,针刺纤维与热解碳的结合良好,密度为1.69 g/cm3的C-HSF/C复合材料界面处的剪切强度达到16.7 MPa.
